  • Please help me understand this PHP script.Noob here

    - by NissGTR
    I'm learning PHP,MySQL and came across this function today function get_director($director_id) { global $db; $query = 'SELECT people_fullname FROM people WHERE people_id = ' . $director_id; $result = mysql_query($query, $db) or die(mysql_error($db)); $row = mysql_fetch_assoc($result); extract($row); return $people_fullname; } I understand what functions are and I've created a few while learning PHP.But this one is a bit more complicated.I can't understand the WHERE people_id = ' . $director_id I'm new to MySQL.I guess the single quote ends the MySQL statement?And then it is concatenated with the argument? Please help me out.

  • Why use shorter VARCHAR(n) fields?

    - by chryss
    It is frequently advised to choose database field sizes to be as narrow as possible. I am wondering to what degree this applies to SQL Server 2005 VARCHAR columns: Storing 10-letter English words in a VARCHAR(255) field will not take up more storage than in a VARCHAR(10) field. Are there other reasons to restrict the size of VARCHAR fields to stick as closely as possible to the size of the data? I'm thinking of Performance: Is there an advantage to using a smaller n when selecting, filtering and sorting on the data? Memory, including on the application side (C++)? Style/validation: How important do you consider restricting colunm size to force non-sensical data imports to fail (such as 200-character surnames)? Anything else? Background: I help data integrators with the design of data flows into a database-backed system. They have to use an API that restricts their choice of data types. For character data, only VARCHAR(n) with n <= 255 is available; CHAR, NCHAR, NVARCHAR and TEXT are not. We're trying to lay down some "good practices" rules, and the question has come up if there is a real detriment to using VARCHAR(255) even for data where real maximum sizes will never exceed 30 bytes or so. Typical data volumes for one table are 1-10 Mio records with up to 150 attributes. Query performance (SELECT, with frequently extensive WHERE clauses) and application-side retrieval performance are paramount.

  • SQL-Join with NULL-columns

    - by tstenner
    I'm having the following tables: Table a +-------+------------------+------+-----+ | Field | Type | Null | Key | +-------+------------------+------+-----+ | bid | int(10) unsigned | YES | | | cid | int(10) unsigned | YES | | +-------+------------------+------+-----+ Table b +-------+------------------+------+ | Field | Type | Null | +-------+------------------+------+ | bid | int(10) unsigned | NO | | cid | int(10) unsigned | NO | | data | int(10) unsigned | NO | +-------+------------------+------+ When I want to select all rows from b where there's a corresponding bid/cid-pair in a, I simply use a natural join SELECT b.* FROM b NATURAL JOIN a; and everything is fine. When a.bid or a.cid is NULL, I want to get every row where the other column matches, e.g. if a.bid is NULL, I want every row where a.cid=b.cid, if both are NULL I want every column from b. My naive solution was this: SELECT DISTINCT b.* FROM b JOIN a ON ( ISNULL(a.bid) OR a.bid=b.bid ) AND (ISNULL(a.cid) OR a.cid=b.cid ) Is there any better way to to this?

  • Snapshot on, still deadlocks, ROWLOCK

    - by Patto
    I turned snapshot isolation on in my database using the following code ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON and got rid off lots of deadlocks. But my database still produces deadlocks, when I need to run a script every hour to clean up 100,000+ rows. Is there a way I can avoid deadlocks in my cleanup script, do I need to set ROWLOCK specifically in that query? Is there a way to increase the number of row level locks that a database uses? How are locks promoted? From row level to page level to table level? My delete script is rather simple: delete statvalue from statValue, (select dateadd(minute,-60, getdate()) as cutoff_date) cd where temporaryStat = 1 and entrydate < cutoff_date Right now I am looking for quick solution, but a long term solution would be even nicer. Thanks a lot, Patrikc

  • Drupal pass argument to page

    - by stotastic
    I have a custom Drupal module displaying some data in a table. Each row has a link which if clicked will delete the relevant row. Specifically, when the link is clicked it will take the user to a confirmation page. This page is really just a drupal form which says 'are you sure' with two buttons: 'Yes', 'No'. I figure I will need to pass the rowID to the confirmation page. My question: What is the typically way to pass data to a new page in Drupal 7? I guess I could just add the rowID to the URL and use the $_GET[] from the confirmation page... I don't think this is very safe and was wondering if there was a better 'Drupal' way. Thanks!

  • How to insert a value based on lookup from another table [SQL]?

    - by Shaitan00
    I need to find a way to do an INSERT INTO table A but one of the values is something that comes from a lookup on table B, allow me to illustrate. I have the 2 following tables: Table A: A1: String A2: Integer value coming from table B A3: More Data Table B: B1: String B2: Integer Value Example row of A: {"Value", 101, MoreData} Example row of B: {"English", 101} Now, I know I need to INSERT the following into A {"Value2", "English", MoreData} but obviously that won't work because it is expecting an Integer in the second column not the word "English", so I need to do a lookup in Table B first. Something like this: INSERT INTO tableA (A1, A2, A3) VALUES ("Value2", SELECT B2 FROM tableB where B1="English", MoreData); Obviously this doesn't work as-is ... Any suggestions?

  • high tweet status IDs causing failed to open stream errors?

    - by escarp
    Erg. Starting in the past few days high tweet IDs (at least, it appears it's ID related, but I suppose it could be some recent change in the api returns) are breaking my code. At first I tried passing the ID as a string instead of an integer to this function, and I thought this worked, but in reality it was just the process of uploading the file from my end. In short, a php script generates these function calls, and when it does so, they fail. If I download the php file the call is generated into, delete the server copy and re-upload the exact same file without changing it, it works fine. Does anyone know what could be causing this behavior? Below is what I suspect to be the most important part of the individual files that are pulling the errors. Each of the files is named for a status ID (e.g. the below file is named 12058543656.php) <?php require "singlePost.php"; SinglePost(12058543656) ?> Here's the code that writes the above files: $postFileName = $single_post_id.".php"; if(!file_exists($postFileName)){ $created_at_full = date("l, F jS, Y", strtotime($postRow[postdate])-(18000)); $postFileHandle = fopen($postFileName, 'w+'); fwrite($postFileHandle, '<html> <head> <title><?php $thisTITLE = "escarp | A brief poem or short story by '.$authorname.' on '.$created_at_full.'"; echo $thisTITLE;?></title><META NAME="Description" CONTENT="This brief poem or short story, by '.$authorname.', was published on '.$created_at_full.'"> <?php include("head.php");?> To receive other poems or short stories like this one from <a href=http://twitter.com/escarp>escarp</a> on your cellphone, <a href=http://twitter.com/signup>create</a> and/or <a href=http://twitter.com/devices>associate</a> a Twitter account with your cellphone</a>, follow <a href=http://twitter.com/escarp>us</a>, and turn device updates on. <pre><?php require "singlePost.php"; SinglePost("'.$single_post_id.'") ?> </div></div></pre><?php include("foot.php");?> </body> </html>'); fclose($postFileHandle);} $postcounter++; } I can post more if you don't see anything here, but there are several files involved and I'm trying to avoid dumping tons of irrelevant code.

  • Remove a DIV using a link

    - by GSTAR
    HTML: <div class="row"> <!-- content --> <a href="#" class="remove">remove</a> </div> JS: $('.remove').click(function(){ $(this).parent().remove(); return false; }); If there is only one DIV it works OK but when there are multiple DIVS (class="row") it won't do anything. No errors are returned either. EDIT: I should add that by default there is only one div - additional divs get dynamically created using a jQuery clone function - perhaps this is why it won't recognise the new link/div?

  • Memory usage of strings (or any other objects) in .Net

  • How to localize numerals?

    - by SoLoGHoST
    Ok, I'm using mathematical equations to output numbers, though, I need this to be compatible for all languages. Currently, all language strings are within a php array called $txt, and each key of the array gets called for that language. I'm outputting the following: Column 1, Column 2, Column 3, and so on, as well as Row 1, Row 2, Row 3, and so on. The calculations are done via php and javascript, so I'm wondering on the best approach for how to support all languages for the numbers only. I don't do the translations, someone else does, but I need to be able to point it to, either the php variable $txt of where the language is defined, or, since the calculations are done via javascript also, I need to somehow store this in there. I'm thinking of storing something like this: // This part goes in the php language file. $txt['0'] = '0'; $txt['1'] = '1'; $txt['2'] = '2'; $txt['2'] = '3'; $txt['4'] = '4'; $txt['5'] = '5'; $txt['6'] = '6'; $txt['7'] = '7'; $txt['8'] = '8'; $txt['9'] = '9'; // This part goes in the php file that needs to call the numbers. echo '<script> var numtxts = new Array(); numtxts[0] = \'', $txt['0'], '\'; numtxts[1] = \'', $txt['1'], '\'; numtxts[2] = \'', $txt['2'], '\'; numtxts[3] = \'', $txt['3'], '\'; numtxts[4] = \'', $txt['4'], '\'; numtxts[5] = \'', $txt['5'], '\'; numtxts[6] = \'', $txt['6'], '\'; numtxts[7] = \'', $txt['7'], '\'; numtxts[8] = \'', $txt['8'], '\'; numtxts[9] = \'', $txt['9'], '\'; </script>'; And than in the javascript function it could grab the correct string for each number like so: // Example Number String below. var numString = "10"; var transNum = ""; for(x=0;x<numString.length;x++) { var numChar = numString.charAt(x); transNum += numtxts[parseInt(numChar)]; } return transNum; The problem with this bit of code is that it groups the numbers, not sure if all languages do that, like the english language does...? Perhaps there's a better approach for this? Can anyone help please? Thanks :)

  • Data validation between SQL replicated tables

    - by Vikram
    Hi All, I am trying to figure out a way to validate the data in my publisher and subscriber in SQL 2005 replication. I thought of using sp_publication_validation, but it needs db_owner permission and we are not allowed to have it in our company. So I did bit more reading and found out about two other SPs that I think work for me. First one is sp_article_validation, which I plan to run on the publisher. For each article that I call this SP, its gonna give the row count and a checksum. With that info, I intend to call sp_table_validation on the subscriber, passing the row count and checksum from the previous SP, there by validating both tables. What do you guys think? Is this a proven way to validate data in replication? There is very little documentation on these SPs. Here is the link: sp_table_validation - http://msdn.microsoft.com/en-us/library/aa239370(v=sql.80).aspx sp_article_validation - http://msdn.microsoft.com/en-us/library/ms177511(v=SQL.90).aspx Thanks for

  • CSS working in IE, but not FF

    Hi guys, I have a very simple css file for my Asp.Net MVC application. body { font-family: Arial, Helvetica, sans-serif; font-size: x-small; color: #663300; } input { font-family: Arial, Helvetica, sans-serif; font-size: x-small; background-color: #FFFF99; color: #CC6600; border: 1px solid #808000; } .headerRow { background-color: #FFFFCC; border-style: none none dotted none; border-bottom-width: 1px; border-bottom-color: #800000; font-family: Arial, Helvetica, sans-serif; font-size: x-small; font-weight: bold; text-align: left; vertical-align: middle; text-transform: uppercase; } The Body is working well in both... as is the input. However, the headerRow isn't working in FF, yet works well in IE. Here it is, being used: <table width="700" border="0" cellspacing="1" cellpadding="2"> <tr class="headerRow"> <td> Transaction Date </td> <td> Type </td> <td> Category </td> <td> Budget Assignment </td> <td> Cost Center </td> <td align="right"> Amount </td> </tr> The header row just displays as normal body text though...

  • MATLAB, time match filter

    OK, I am still getting the hang of MATLAB. I have two files in different format. One Excel file. data1.xls, size= 86400 X 62. It looks like: Date/Time par1 par2 par3 par4 par5 par6 par6 par7 par8 par9 08/02/09 00:06:45 0 3 27 9.9 -133.2 0 0 0 1 0 Another file, data2.csv, size = 144 X 27. (If nothing is missing.)

  • Dynamic SQL Rows & Columns...cells require subsequent query. Best approach?

    - by Pyrrhonist
    I have the following tables below City --------- CityID StateID Name Description Reports --------- ReportID HeaderID FooterID Description I’m trying to generate a grid for use in a .Net control (Gridview, Listview…separate issue about which will be the ‘best’ one to use for my purposes) which will assign the reports as the columns and the cities as the rows. Which cities get displayed is based on the state selected, and is easy enough SELECT * FROM CITIES WHERE STATEID=@StateID However, the user is able to select which reports are being generated for each City (Demographics, Sales, Land Area, etc.). Further, the resultant cells (City * Report) is a sub-query on different tables based on the city selected and the report. Ie. Column Sales selected yields SELECT * FROM SALES WHERE CITYID=@CityID I’ve programmed a VERY inelegant solution using multiple queries and brute-forcing the grid to be created (line by line, row by row creation of data elements), but I’m positive there’s got to be a better way of accomplishing this…? Any / all suggestions appreciated here as the brute force approach I’ve gotten is slow and cumbersome…and this will have to be used often by the client, so I’m not sure it’ll be acceptable in it’s current implementation.

  • Bash script to find a directory, list it's contents and sub-folders info

    - by lithiumion
    Hi I want to write a script that will: 1- locate folder "store" on a *nix filesystem 2- move into that folder 3- print list of contents with last modification date 4- calculate sub-folders size This folder's absolute path changes from server to server, but the folder name remains the same always. There is a config file that contains the correct path to that folder though, but it doesn't give absolute bath to it. Sample Config: Account ON DIR-Store /hdd1 Scheduled YES ?According to the config file the absolute path would be "/hdd1/backup/store/" I need the script to grep the "/hdd1" or anything beyond the word "Config-Store", add "/backup/store/" to it, move into folder "store", print list of it's contents, and calculate sub-folders size. Until now I manually edit the script on each server to reflect the path to the "store" folder. Here is a sample script: #!/bin/bash echo " " echo " " echo "Moving Into Directory" cd /hdd1/backup/store/ echo "Listing Directory Content" echo " " ls -alh echo "*******************************" sleep 2 echo " " echo "Calculating Backup Size" echo " " du -sh store/* echo "********** Done! **********" I know I could use grep cat /etc/store.conf | grep DIR-Store Just don't know how to get around selecting the path, adding the "/backup/store/" and moving ahead. Any help will be appreciated

  • Archiving rows dynamically

    - by Serge
    I was wondering what would be the best solution to dynamically archive rows. For instance when a user marks a task as completed, that task needs to be archived yet still accessible. What would be the best practices for achieving this? Should I just leave it all in the same table and leave out completed tasks from the queries? I'm afraid that over time the table will become huge (1,000,000 rows in a year or less). Or should I create another table ie task_archive and query that row whenever data is needed from it? I know similar questions have been asked before but most of them where about archiving thousands of rows simultaneously, I just need to know what would be the best method (and why) to archive 1 row at a time once it's been marked completed

  • Left outer joins that don't return all the rows from T1

    - by Summer
    Left outer joins should return at least one row from the T1 table if it matches the conditions. But what if the left outer join performs a join successfully, then finds that another criterion is not satisfied? Is there a way to get the query to return a row with T1 values and T2 values set to NULL? Here's the specific query, in which I'm trying to return a list of candidates, and the user's support for those candidates IF such support exists. SELECT c.id, c.name, s.support FROM candidates c LEFT JOIN support s on s.candidate_id = c.id WHERE c.office_id = 5059 AND c.election_id = 92 AND (s.user_id = 2 OR s.user_id IS NULL) --This line seems like the problem ORDER BY c.last_name, c.name The query joins the candidates and support table, but finds that it's a different user who supported this candidate (user_id=3, say). Then the candidate disappears entirely from the result set.

  • Does SELECT COUNT(*) work with MySQLi prepared statements?

    - by wordman
    I'm working on a test page and am using MySQLi prepared statements in my queries after reading they make my code safe from SQL injection. I have been successful with prepared statements so far with retrieving data from my DB, that all works great. What I want to do now is count the number of galleries within a project using SELECT COUNT(*). That's it. Without using a prepared statement, my old query looked like this: // count number of galleries per project $conn = dbConnect('query'); $galNumb = "SELECT COUNT(*) FROM pj_galleries WHERE project = {$pjInfo['pj_id']}"; $gNumb = $conn->query($galNumb); $row = $gNumb->fetch_row(); $galTotal = $row[0]; But for all my reading and searching the internet, I can not find out the proper way to write this as a prepared statement. I'm no PHP whiz here, and not coding daily isn't helping my skills. If I've missed anything please ask. Many thanks!

    I have this html code: <tr> <td><label><input type="text" name="id" class="DEPENDS ON info BEING student" id="example">ID</label></td> </tr> <tr> <td> <label> <input type="checkbox" name="yr" class="DEPENDS ON info BEING student"> Year</label> </td> </tr> But I don't have any idea on how do I check this checkboxes if they are checked using php, and then output the corresponding data based on the values that are checked. Please help, I'm thinking of something like this. But of course it won't work, because I don't know how to equate checkboxes in php if they are checked: <?php $con = mysql_connect("localhost","root","nitoryolai123$%^"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("school", $con); $id = mysql_real_escape_string($_POST['idnum']); if($_POST['id'] == checked & $_POST['yr'] ==checked ){ $result2 = mysql_query("SELECT * FROM student WHERE IDNO='$id'"); echo "<table border='1'> <tr> <th>IDNO</th> <th>YEAR</th> </tr>"; while($row = mysql_fetch_array($result2)) { echo "<tr>"; echo "<td>" . $row['IDNO'] . "</td>"; echo "<td>" . $row['YEAR'] . "</td>"; echo "</tr>"; } echo "</table>"; } mysql_close($con); ?>
